Abstract

The paper proposes existing calculation methods and new designs of high-performance solid raft foundations with symmetric and non-symmetric cutouts (non-contact areas in the middle) in the bottoms for lightweight tower-type structures such as wind turbines, tower cranes, telecommunications aerials and others that are capable of taking significant eccentric loads with observance of the edge pressures on the soil base. An example of calculation for various alternate designs of tower crane foundations has been given, which shows the advantages of using foundations with a cutout in the bottom, ultimately leading to a significant saving in concrete consumption (over 50%) for the foundation depending on the design load on the soil base and its bearing capacity.
